1. Check for the marker's colour indicated on teh TOP and 
the actual color of the Marker
2. Check for the Ink Quality.
3. Check for the Ink Quntity.
4. Check for the Brand Name and Logo display on the marker.
5. Check for the cap that should easily Fit to marker.
6. Ink of Marker should not spread during writing on Board.
7. Check for the Temporary/Permanent marker.
8. If the marker is Temporary, then anything written on the 
board using this marker should be erasable with duster.
9. If the Marker is Permanent, Then written should not be 
erasable with dry duster.
10. If the Marker is Permanent, then written text on board

Thanks :-)

1. Check the color of the marker.
2. Check the holding position of the marker.
3. Check the point(nib) of the marker.
4. Check Uniform spread of ink.
5. Check the marker, if we use it continuously, (Chk the ink
if it comes out).
6. Check the tightness of the cap.
7. Check what happen if we open and close the cap repeatedly.
8. Check can we refill the to the marker.
9. Check the logo of the company on the marker.
10.Try to use the marker after the ink is over in the
marker.(to check the finish of ink)
11. Fill the water into it, & then try to write.
12. write & see if the ink is erasable or not.

1. Try putting other colored ink in the marker and check 
for marker's resistance and also try the output on 
whiteboard.

We can also have the following stress cases:
1. Drop the marker from a distance and check whether the 
marker writes on the board.
2. Add some room temparatures and try writing the marker.
3. Write the marker over already written board.
4. Feed the marker to a machine which has exponential 
writing speed when compared to avg human and then run it to 
write on whiteboard.

Performance:
1. Bring fresh marker, Write continuously till the ink is 
over. Calculate the time and check with the actual 
requirement.
2. Open the marker, leave it for some time and then close 
it and try writing. Check the performance.
3. Basic performance checks like: 
Time taken for refilling; 
Time taken for removing and closing the cap;
Time taken for the marker getting ready for writing after 
refilling.
